Abstract
The utility model discloses a kind of light leakage led backlight module, comprise LGP, described LGP comprises the reflecting surface and the exiting surface that are oppositely arranged up and down, the side surface of described LGP between described reflecting surface and described exiting surface is incidence surface, described LGP all the other side surfaces between described reflecting surface and described exiting surface are light leakage face, described light leakage face comprises the lower inclined plane that the ramp side from described exiting surface crossing with described ramp that extend obliquely upward from the side of described reflecting surface oliquely downward extends, on described ramp and described lower inclined plane, be respectively equipped with multiple V-type grooves, also comprise the leakproof tabula rasa wrapping on described light leakage face.V-type groove has increased incidence angle when light arrives inclined-plane, has reduced or eliminated light leak, and leakproof tabula rasa has further prevented the generation of light leak.
Description
Technical field
The utility model relates to a kind of led backlight module.
Background technology
LED-backlit source refers to the backlight that is used as LCDs with LED, the light that Led distributes is passing after LGP, Journalistic to flexible PCB and be blocked, separately has part to be stopped by shading adhesive tape, but also has part to cause light leakage phenomena through diffusion sheet, brightening piece.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of light leakage led backlight module that can effectively avoid light leak.
For solving the problems of the technologies described above, the technical solution of the utility model is: light leakage led backlight module, comprise LGP, described LGP comprises the reflecting surface and the exiting surface that are oppositely arranged up and down, the side surface of described LGP between described reflecting surface and described exiting surface is incidence surface, described LGP all the other side surfaces between described reflecting surface and described exiting surface are light leakage face, described light leakage face comprises the lower inclined plane that the ramp side from described exiting surface crossing with described ramp that extend obliquely upward from the side of described reflecting surface oliquely downward extends, on described ramp and described lower inclined plane, be respectively equipped with multiple V-type grooves, also comprise the leakproof tabula rasa wrapping on described light leakage face.
As preferred technical scheme, described leakproof tabula rasa comprises plate body, and the side surface that described plate body is close in described light leakage face is provided with the V-type projection with described V-type groove fit.
Owing to having adopted technique scheme, light leakage led backlight module, comprise LGP, described LGP comprises the reflecting surface and the exiting surface that are oppositely arranged up and down, the side surface of described LGP between described reflecting surface and described exiting surface is incidence surface, described LGP all the other side surfaces between described reflecting surface and described exiting surface are light leakage face, described light leakage face comprises the lower inclined plane that the ramp side from described exiting surface crossing with described ramp that extend obliquely upward from the side of described reflecting surface oliquely downward extends, on described ramp and described lower inclined plane, be respectively equipped with multiple V-type grooves, also comprise the leakproof tabula rasa wrapping on described light leakage face.V-type groove has increased incidence angle when light arrives inclined-plane, has reduced or eliminated light leak, and leakproof tabula rasa has further prevented the generation of light leak.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the enlarged drawing at I place in Fig. 1;
Fig. 3 is the structural representation of another kind of leakproof tabula rasa in the utility model embodiment.
Detailed description of the invention
As depicted in figs. 1 and 2, light leakage led backlight module, comprise LGP 1, described LGP 1 comprises the reflecting surface 2 and the exiting surface 3 that are oppositely arranged up and down, the side surface of described LGP between described reflecting surface 2 and described exiting surface 3 is incidence surface, described incidence surface is relative with LED light source, described LGP all the other side surfaces between described reflecting surface and described exiting surface are light leakage face, described light leakage face comprises the lower inclined plane 5 that ramp 4 side from described exiting surface crossing with described ramp 4 that extend obliquely upward from the side of described reflecting surface oliquely downward extends, on described ramp 4 and described lower inclined plane 5, be respectively equipped with multiple V-type grooves 6, also comprise the leakproof tabula rasa 7 wrapping on described light leakage face.
Preferably, as shown in Figure 3, described leakproof tabula rasa 7 comprises plate body, and the side surface that described plate body is close in described light leakage face is provided with the V-type projection 8 with described V-type groove fit.
V-type groove 6 has increased incidence angle when light arrives inclined-plane, has reduced or eliminated light leak, and leakproof tabula rasa 7 has further prevented the generation of light leak.
To the above-mentioned explanation of the disclosed embodiments, make professional and technical personnel in the field can realize or use the utility model.To be apparent for those skilled in the art to the multiple amendment of these embodiment, General Principle as defined herein can, in the situation that not departing from spirit or scope of the present utility model, realize in other embodiments.Therefore, the utility model will can not be limited to these embodiment shown in this article, but will accord with principle disclosed herein and features of novelty the widest consistent scope.
